debugd: remove org.chromium.debugd.RunModemCommand D-Bus API

The org.chromium.debugd.RunModemCommand D-Bus API was used by the
'modem' script to send AT commands to some old modems that we supported,
which are not longer supported or needed. CL:1262881 removed those
commands from the modem script. This CL removes the
org.chromium.debugd.RunModemCommand D-Bus API from debugd as well as the
send_at_command.sh helper script.

BUG= chromium:892455 
CQ-DEPEND=CL:1263178
TEST=Verify that org.chromium.debugd.RunModemCommand no longer exists.
